tail() function
The tail()
function limits each output table to the last n
records.
The function produces one output table for each input table.
Each output table contains the last n
records before the offset
.
If the input table has less than offset + n
records, tail()
outputs all records before the offset
.
tail(n: 10, offset: 0)
Parameters
n
(Required) The maximum number of records to output.
offset
The number of records to skip at the end of a table table before limiting to n
.
Default is 0
.
tables
Input data.
Default is piped-forward data (<-
).
Examples
The following example uses data provided by the sampledata
package
to show how tail()
transforms data.
- Output the last three rows in each input table
- Output the last three rows before the last row in each input table
Output the last three rows in each input table
import "sampledata"
sampledata.int()
|> tail(n: 3)
Output the last three rows before the last row in each input table
import "sampledata"
sampledata.int()
|> tail(n: 3, offset: 1)
